I'm recently bought a Scythe Ninja Copper, but it's missing the LGA 775 retention kit, which includes a backplate and a bracket.
Shown here:X-bit labs - I Am Legend: Scythe Ninja Copper Cooler Review (page 4)
It comes with a SCURK1 but I would not require anything else in the kit.
Anyone who has a Scythe product but does not use the LGA 775 retention kit please reply.
